本文叙述了电感耦合等离子体原子发射光谱法(ICP-AES)测定硅酸盐岩石中的主要元素的分析方法及结果。我国ICP-AES对痕量分析工作已广泛开展,但在硅酸盐主要元素分析方面如何发挥仪器潜力的报导并不多。本文的目的是提供一个同时测定硅酸盐岩石及类似样品的十种主要元素的方法及结果。方法的精密度和准确度均能满足地球化学工作的要求。 实验部分 光谱仪及工作条件
This paper describes the analytical methods and results of ICP-AES for the determination of major elements in silicate rocks. ICP-AES has been widely used in trace analysis in China. However, there are not many reports on how to utilize the potential of instruments in the analysis of major elements of silicate. The purpose of this paper is to provide a method and result for the simultaneous determination of ten major elements of silicate rocks and similar samples. The precision and accuracy of the method can meet the requirements of geochemical work. Experimental part of the spectrometer and working conditions
